Comm, assignors to The Atwood Machine Company, Stonington, Conn, a corporation of New Jersey I Application June 11, 1931, Serial No. 141,102 4 Claims. (01.118-11) This invention relates to twisting machines for textile yarn and more particularly relates to means to enclose the twisting spindles and their bobbins; v p

' An object of the present invention is to provide an enclosure for the spindleof a twisting machine adjacent the bobbin carrying portion, the member forming the enclosure being supported so that it may swing with the spindle into and out of: driving or operative position and always remain co-axial with the spindle.

Another object of the invention is to mount a supporting basemember for the enclosing memher of ring form, disposed coaxially of the spindle and supported upon the pivot about which spindie swings. j

With the above and other objects in view the invention may include the features of construction and operation set forth in the following specification and illustrated in the accompanying drawing.

In the accompanying drawing annexed hereto and forming a part of this specification, we have shown the invention embodied in a swinging type spindle of standard or conventional form but it will be understood that the invention can be otherwise embodied and that the drawing is not to be construed as defining or limiting the scope of the invention, the claims, appended to this specification being relied upon for that purpose.

In the drawing: 1 Fig. 1 is a complete longitudinal sectional view of a swinging type twisting spindle to which the improved form of enclosure has been applied;

Fig. 2 is a fragmentary outside view of a por- 7 tion of the spindle and its enclosure, and

Fig. 31s a sectional view taken on line 2-2 of Fig. i.

In the above mentioned drawing, there has been shown but one embodiment of the invention which is now deemed preferable, but it is to be understood that changes and modifications may be made within the scope of the appended claims without departing from the spirit of the invention.

Briefly, and in its preferred aspect, the invention may include the following principal parts: first, a supporting bracket; second; a swinging swingin member supported on said bracket by means of a vertical pivot; third, a bolster secured to. the

member; fourth. a spindle'assembly rotatably mounted in said bolster; fifth, a ring-like base member secured to the pivot about which the swinging member pivots; sixth, a cylindrical member detachably retained in thebase member and surrounding the upper portion of the spindle dle.

Referring more indetail to the figures of the drawing there is provided a bracket l0 adapted for attachment by any suitable means (not shown) to a textile twisting machine of any standard or conventional form. This bracket i0 may have an extension preferably directly secured thereto as shown in Fig. 3. The extension H has spaced aligned holes through which the pivot shaft l2 extends and forms a bracket support for the spindle supporting and rotating means and also for the enclosure for the bobbin supporting portion of the spindle.

I and enclosing the bobbin supported on the spin- Keyed or pinned to the pivot shaft I2 is a swinging member ll within which is supported a bolster member l5 within which is rotatably supported the spindle it on whichis secured a whorl l'l. As the swinging member ll, the bolster l5 and the rotating spindle l6 are or may be of standard or usual construction, it will beunnecessary to further describe or illustrate these parts of the construction. It will be understood a ring-like base member 2| surrounding the spindle l6 shortly above the whorl IT. This member 2| is provided with a cylindrical bearing surface on which is supported an enclosing member 22. The enclosure 22 is preferably of thin cylindrical form and preferably is formed of molded material such as bakelite.

To secure the enclosure 22 in position on the base 2i a plurality of short helical projections may be provided upon the outside cylindrical bearing surface of the base and upon the internal surface of the enclosure adjacent its lower edge.

By tumingthe enclosure 22 when placing it upon the base 2] the enclosure and base will be detachably but firmly locked together.

Swinging movement of the spindle I6 and at ,tached parts with the member II to engage and disengage the whorl I! with the spindle driving member in the usual way also serves to swing the base member 2| and the enclosure 22. The

enclosin'efl is therefore at all times maintained concentric with the spindle l6.

Inthe drawingthe enclosure 22 hasbeenshown conical at its upper end and to have a central opening 23 through which the yarn or thread being twisted may pass as it is being drawn upward. from the bobbin on the spindle l6.

We claim as ou'r'invention:

1. Spindle enclosing means for twisting machines comprising in combination, -a spindle bracket, a shaft supported in said bracket for oscillatory movement upon a vertical axis, a swinging member secured to said shaft, a ring-like base member secured to said shaft, and a spindle enclosure detachably secured to said base member.

2. Spindle enclosing means for twisting machines comprising in combination, a spindle bracket, a shaft supported in said bracket for oscillatory movement upon a vertical axis, a swinging member secured to said shaft, a spindle and supporting and rotating means therefor on said swinging member, a ring-like base member surrounding said spindle and secured to said shaft, and an enclosure for said spindle detachably supported on said base member.

s. Spindle enclosing means in twisting machines comprising in combination, a spindlebracket, a swinging member pivotally supported within said bracket for movement about a vertical axis, spindle supporting and rotating means on said swinging member, a ring member surrounding an intermediate portion of said spindle end, and a bobbin enclosing member resting upon said ring member and detachably retained there i. Spindle enclosing means for twisting machines comprising in combination, aspindle bracket, a swinging member pivotaliy supported within said bracket for movement about a vertical axis, a spindle bolster secured in said swingand secured to said pivotal support at its upper ing member, a spindle rotatable within said bolster and having a whorl thereon, a ring member surrounding the upper portion of said whorl and secured to the pivotal support for said member and a bobbin-enclosing member having its lower end removably retained within said WALTER.
